Resident Evil: Survival Unit – ACE Event Guide (How to Score Big Every Day)

The ACE Event in Resident Evil: Survival Unit is one of the best ways to stack rewards, speed up your growth, and push your account forward without spending. But—just like in every other survival/base-builder game—timing is everything.

If you just blindly do tasks whenever they pop up… you’re going to waste points, waste speedups, and fall behind the players who know how to line everything up properly.

This guide walks you through Day 1 to Day 5, what each day wants from you, and how to prepare ahead so you never scramble last-minute.

Remember this event repeats as well so.. get ready!

Let’s get into it.

⭐ How ACE Works (Quick Breakdown)

Every day the ACE event rotates into a new scoring category, and each category gives different amounts of points depending on what actions you take.

Your goal is to:

• Save the right tasks for the right days

• Stockpile resources ahead of time

• Use speedups only when the points are worth it

• Plan big upgrades on specific scoring days

Mastering ACE basically turns your account into a turbo booster. If you complete most days, you’ll stay ahead of 95% of your server.

DAY 1 – INCREASE COMBAT POWER (Buildings + Research Only)

Day 1 is very specific: only Construction and Research power count.

✔ What scores:

• +1 Combat Power from Construction = 45 pts

• +1 Combat Power from Research = 45 pts

🔥 Strategy

This is one of the most important ACE days because it’s where you can dump large upgrades for big points.

Save these upgrades for Day 1:

• Command Center upgrades

• Hospital

• Barracks upgrades

• Tech Lab research

• Troop Power research

SUPER IMPORTANT:

Do NOT finish big upgrades the day before.
Leave them 1–5 minutes from completion, then speed-finish them on Day 1

COMMON MISTAKE DAY 1 – 
Upgrading low-value buildings
Small buildings (farms, oil pumps, etc.) barely give combat power.  Your warehouse gives none. Players waste speedups on them and miss major points from Command Center, Barracks, Hospital, and Research.

DAY 2 – EARN POINTS / SPEND HERO FILES / GATHER

Day 2 is mixed points: gathering + hero files + roulette.

✔ What scores:

• Spin roulette – 90,000 pts

• Use Rare File – 4,000 pts

• Use Epic File – 14,000 pts

• Use Legendary File – 35,000 pts

• Gather 200 Food / Lumber / Iron / Oil – 15 pts each

🔥 Hero File Strategy

• SAVE all your files for this day.

• Using even a few Epics/Legendaries can shoot you into high reward tiers.

🔥 Gathering Strategy

• The points per gather aren’t huge, but:

  • Fill all marches

  • Send to highest nodes

  • AFK gather all day

TIP:
Everyone gets a free roulette spin for several days, but ONLY this day counts for the ACE event. You can buy a package or use GEMS to buy a package. This can give you a good chance of getting Carlos.

COMMON MISTAKE DAY 2 –
Your marches should be gathering as Day 2 begins. Time it so they finish as Day 2 starts.  Many players start late and miss thousands of passive points.

DAY 3 – TROOP TRAINING

Day 3 is all about troop training. Higher tiers = more points.

✔ What scores points:

• Tier 1 = 90 pts

• Tier 2 = 120 pts

• Tier 3 = 180 pts

• Tier 4 = 265 pts

• Tier 5 = 385 pts

• Tier 6 = 595 pts

• Tier 7 = 830 pts

• Tier 8 = 1,130 pts

• Tier 9 = 1,485 pts

🔥 Strategy

• DO NOT train troops the day before.

• Queue up all barracks, then speed at the right moment.

• Higher tiers give more points per resource spent.

TIP:
If you’re low on resources, train lower tiers so you still score something.
If you’re pushing for max points? Save resources + speedups for this day only.

COMMON MISTAKE DAY 3 – 
Only training low tiers
Low tiers are cheaper, but they give terrible points per resource. You should prioritize your highest unlocked tier whenever possible.

Day 4 DEFEAT INFECTED / ABERRATIONS

Day 4 is simple and honestly the easiest day to max if you prepare ahead.

✔ What scores points:

• Defeat normal Infected / Aberrations – 30,000 pts

• Defeat B.O.W. (Rally Boss) – 90,000 pts

🔥 Strategy

• Burn stamina efficiently.

• Use your highest-level march – you get the same points no matter what level monster you hit.

• Rally B.O.W. with your alliance for huge chunks of points.

TIP:
Dumping stamina on Day 4 is worth it. Don’t waste it the day before. Let it sit capped so you can get more kills.

COMMON MISTAKE DAY 4 –
Hitting high-level monsters only
You get the same ACE points for every kill. Hitting a level 30 Aberration doesn’t give more ACE points than hitting a level 1. Hit whatever you can kill quickly.

DAY 5 – FULL POWER DAY (Construction + Research + Troop Training)

This is the “all points combined” day –  kind of a mini-merge of Days 1 and 3.

✔ What scores:

• Combat Power from Construction = 30 pts

• Combat Power from Research = 30 pts

• Combat Power from Troop Training = 20 pts

🔥 Strategy

This day is where you dump:

• Any Remaining speedups

• Any big construction you saved

• Troop training bursts

• Research power spikes

If you build your week correctly, this day is massive for total event ranking.

COMMON MISTAKE DAY 5 –
Not saving anything for Day 5
This day is your “catch-all” power day. If you’ve blown everything earlier in the week, you’ll have nothing left to score with.

BONUS: WHY BOTHER WITH ACE’S PROOF EVENT?

A smart alliance uses ACE as a training cycle that prepares everyone for major war events.

ACE is basically a disguised 5-day war preparation program.

An alliance that completes ACE daily will walk into any event – Cross-Server War, Territory fights, Alliance vs Alliance, World Boss – significantly stronger.

An alliance that ignores ACE will always be behind, always weaker, always reactive instead of proactive.

FINAL TIPS FOR MAXING ACE EVERY WEEK IN RESIDENT EVIL SURVIVAL UNIT

✔ Save everything for the correct day

Don’t waste files, speedups, or upgrades on the wrong day.

✔ Use an alt/farm account to funnel resources

Especially on Troop Training Day. Don’t have a farm yet? Read our guide. 

✔ Always be upgrading something

Even if it takes 1–2 days – plan to finish it on Day 4 or Day 5.

✔ Track stamina

Day 4 is pure free points.

✔ Don’t rush construction early in the week

Everything should finish on scoring days.
